To all wir/0771, it may concern: p

Beit known that we, FRANCIS G., SUSEMIHL and AUGUSTUS Tonner, citizensof the United States 4of America, residing at'Detroit, in the county ofWayne and State of Michigan,'have invented certain new and usefulImprovements in Car Side Bearings, of which the following is aspecification, referencebeinghad Vtherein to the accompanying drawings.

This invention relates toY that class of side bearings in whichantifriction-rollers are interposed between the truck and lbody bolsterson opposite sides of the center bearing.

The object' of our invention is to make a roller-bearing of simpleconstruction and not liable to get out of order; and to this'end theinvention consists of a casing carried by thebody-bolster and inclosingal series of Vdisconnected roller-trucks guided upon a track within thecasing and coperating with a bearing on the truck-bolster' to formananti'- friction side bearing, all as more fully hereinafter described,and shown in the accompanying drawings, in whichi Figure l is a sideelevation of the bearing 'with thefrontwall of the casing broken away toshow the interior of the casing. Fig'.- 2 is a top plan of the bearing;Fig. 3, across-section of the bearing. Fig. 4 is a detached plan Vof oneof the roller-trucks, vand Fig.v 5V is an en'd elevation ofrFig. 4.

Aand B represent the outer ends of a bodybolster and a truck-bolster,respectively, between which our improved side bearingis interposed,thebolsters being, as usual, provided with a center bearing.- (Notshown.) C is the casing', secured in any suitable manner to the underside of the body-bolster, and D represents a series ofroller-trucksinclosed in said casing free to travel. Each roller-truckconsists of a pair of tapering rollers a`,for1ned with journals b, andof la rigid frame coinposed oftwo side bars c c', formed with bearingsd, in which the .rollers are removably journaled, and of a cross-bar e,connecting the side bars between the rollers. The side bars c c.. arerounded off at the ends, and the journals l) of 4 the rollers projectbeyond the side bars of the truck-frame.r The side bars are alsoprovided with hoods'jwhich project over the top yportions 'of theprojecting ends of the rollers, but leave the lower portions exposed.These hoods strengthen the sidev bars. at the bearings and at the sainetime form stops to prevent the endwise movement of the roller in thetruck-frame. truck is adapted to form anindependent traveling unit, andthe series of trucks together form an endless'train free to travelwithin the casing around a central core g formed Each rollerthereinandadapted to support a 'plurality core at a distance apart equal to thelength of the bearing-face of the rollers and adapted to guide theroller and mediately `the trucks in a path concentric with the centerbearing. The casing is open on top and bottom and may be cast in onepiece, with the exception of forming the bearing-face for the activerollers ofaseparate steelA plate j. The

sides of the casing at their lower edges are formed or provided withinwardly-proj ectin g retaining-danges i, which prevent therollertrucksfrom falling out in. case the bolster B shouldbe withdrawn.These retaining-flanges,

however, continue upward upon the sides'of the casing in the path of theroller-trucks,

and from being vmere r'etaining-iianges they Vbecome bearing-flanges'11', upon which the projecting ends of the journalsof the rollers y areadapted to travel in rolling contact therewith in passing around theends of the core g, the hoods being suitably cut away to pe mit thistravel;v The anges fz are continued upward sui'i'ciently to guide therollers till they can travel upon the top portion 'of the core, and theyare then-stopped off, so

as to form a clear and unobstructed entrance into the top of the casing,through which the trucks maybe inserted into or removed from the casingwhen the casing is taken oEEI The l flanges e" inl connection with theattened portions of the core thus forni the track on which the rollerstravel whenever alrelative movement between lthe holsters takes place,

, and in whatever direction the movement takes ment takes place' and insuch manner that as soon as each roller is relievedof the load itcommences to travel withits journals upon the flanges i', owing-.to thetendency of the trucks to 'push each other outwardly in passingaround1the ends of the core. In doing so the rollersy are .caused to revolvein a re- `verse directon upon their axis till gravity causes the trucksto drop on top of the core. In passing-over the top the rollers travelupon the core, while the trucks ride upon bearings l, formed between theguide-anges hand the sideof the casing. As the trucks collectively forman endless train in which the individual trucks can havev little or-noindependent travel, itis not necessary that thereshouldbe any connectionbetween the trucks. In fact, vwe find it more desirable that the trucksshould be independent, as it insures greater freedom in travel byallowing the trucks to slightly separate. It also dispenses withunnecessary parts. However, suitable connections between the trucks maybe used without interfering withthe broader featuresv of our invention.The contour and shape of the trnckframe is such that rubhing contactwith the casing will be avoided, and the side bars areof such relativelengths that a line drawn through the extreme end. will pass through thecenter bearing. In-

stead of one cross-bar 'centrally uniting the side bars the side barsmay be united by cross-bars near the ends.

It is obvious that our improved beat-in g in.-

stead of being carried by the body-bolster may beA carried upon .thetruck-bolster, and any modification with this end in view we deem to bewithin the scope of our invention. The advantage of roller-bearings inwhich the rollers travel in a continuous path over those in which therollers are stationary or travel in the are of a circle only is wellunderstood.; but in all construction of the former kind of which we areaware it is possible for the rollers to skew-that is, they get ont ofradial alinement with the center bearingand thenk they becomeinoperative as an anti'- friction ;bearing. In our constructionthiscannot occur,as the rollers are rigidly held in alinement by beingjournaled in rigid truckframes, two or more. It will also beseen thatour construction is simple and the rollers are adapted to'travel with aminimum of friction.
